Mr Miller and Mr Valasek, car hackers, prompted a recall of 1.4m Fiat Chrysler vehicles last year after a magazine article detailed how they accessed a radio to disable a Jeep’s transmission as it drove along a road. Now they are back at work, showing that with initial physical access, they can trick a car into speeding up, braking, or force it to ignore a request from the emergency parking brake.
 But they do not think carmakers are taking them seriously. “They all say their car couldn’t be affected,” the pair said, laughing on stage at this month’s Black Hat cyber security conference.
